Application filed January 12,1912." Serial No. 870,857.".

a citizen of the United States,residing at LittleFalls, in the county of Herkimer and State of New York, have invented a new and useful Improvement ,in sterilizing Tanks, of which the following .is a specification.

,Tlns invention relates to a tank or receptacle for containing an antiseptic'or sterillzing solution in which parts OflIlllkll'lg machines and similar articles can be kept immersed when not 1n use.

One of the principal objects [which are sought to beacconiplished by the'use [of milking machines isto produce milk oflow bacterial content. It has beenfound that for the accomplishment of this result it is of great importance that the rubber "tubes and connecting parts, 1 such as-teat cups,

mouth pieces and connectorsfwhennot' in use, should be keptimmerse'd in an antiseptic solutlon 1n order to destroy the bac-v term or germs in thesame.

in the same in suchafposition that the air will freely escape and the tubes and other A parts will become filled with the liquid,

As illustrating one type or style of tubes and fittings for which this tank is designed, reference is made toPatent No. 979,174 Dec. 20, 1910, Lane, which shows a main 1 rubber tube extending from themilk vessel to a connector or manifold fitting and branch rubber tubes extending from thls connector to the teat cups.

In the accompanying drawings: Figure, 1,

is a sectional elevation of the preferred construction of this improved tank. Fig. 2 is a detached perspective view of the guide tube removed from the tank. Fig. Bis a partly sectional elevation ofamodified construction of the tank. 1

Like reference characters refer to like parts in the several figures.

Referring to the construction of the tank represented in Figs. 1 and 2, the tank comprises an upper large portion A which is designed to receive the teat cups, branch tubes,

connectors and the portions of the main tubes which are adjacent to the connector,

the pulsators.

Theobject of this ,lnventlon is toproduce a tank or receptacle which is suitable for containing such a solutlon .or liquid and.

and a lower contracted port-ion B which is designed to receive the remaining. portions ofthe main tubes. The lower portion constitutes an upright hollow column, preferably of circular cross section, although other cross sections may be used, upon which the" upper portion, also circular, or of corre sponding cross. section, is supported.

outer annular portion G which rests loosely uponthetank, and an inner central portion D which is hinged to theiannular portion so I thatit 'can'be swungup ordown. The ank nular portion C isfprovided on its under side near its inner edge with hooks 0 from which the tubes are suspended by means of the loops with which the connector'sare usually provided for attachment-to the bails of represents the connectors, e theirloops,

F.the mainmilk tubes, G the teat cups, and

,o the branchtubes." [.VVhen 'the tubes have v.beenso suspended in the tank the branch pipes and teat cups hang down from the tracted part of the tank, a guide tube or eX-' tension fl is provideduvhich is preferably.

removable andarranged with its lower por tionv in the lower portion B of the tank. This guide tube extends into the upperportion A to such a distance from the cover that connector'in the upperenlarged part A of Y the main rubber tubes can be conveniently introduced into this guide tube and through the latter into the lower portion B of the tank. This ,guidetube may be supported in any suitable manner, for instance, on the bottom of theupper portion A by a collar h secured to the tube and provided with open ings, z" for theipassage of the liquid. hen the cover andythe guide tube'have been-removed, the interior of the tank is freely acd the portion B. .A drain cock Z is provided I at thebottom of the tank through which the 1 liquid may as desired.

be withdrawn wholly or in part,

In the modified construction represented in Fig. 3, the upper portion A ofthe tank is provided near its top with an annular shoulder or ledge a upon which rests loosely a spider or plate L which is provided-with hooks Z to which the connectors are attached.

In the improved tank herein described and illustrated, the tubes are so suspended and arranged that air is not caught or im prisoned in any part of the same and the sterilizing or antiseptic liquid, which may be of any suitable character or composition, completely fills every part of the tubes'and branch tubes and comes in contact with every part of the inner and outer surfaces thereof, thereby securing a complete sterilization of these .parts. The main tubes and the branch tubes hang down from the connector and the air escapes upwardly through the connector whichis provided with a 1011- gitudinal air passage through it, as described in the patent above referred to.

The construction of the vtankfir'epresented in Fig. l has, many desirable features, among them that the operator can readily introduce and remove the tubes without bringing his hands in contact V with the liquid; t

The contractedlower portion ofthe tank serves to hold the main tubes closely in positi'on, prevents the different tubes from becoming curled and from interfering with each other, reduces the weight, bulk and cost of the apparatus, and reduces the volume of liquid contained therein.

I claim as my invention:

1. A sterilizing tank comprising a'hollow column and an enlarged top portion communicating therewith and 'comprisinga botextends outwardly from the upper portion of said column, a peripheral wall extending upwardly from said bottom, a cover resting on said peripheral wall, and devices in said top portion for suspending tubular articles within said top portion and hollow column. i

V 2. .A sterilizing tank comprising a hollow column and an enlarged top portion communicating therewith and comprising a bottom which extendsioutwardly from the upper portion of said column, a peripheral wall extending upwardly from said bottom,

and a tubular guide forming an upward continuationof said column and terminating within said top portion.

3. A sterilizing tank comprising a hollow column and an enlarged top portion communicating therewith and comprising a bottom which extends outwardly from the upper "portion of said column, a peripheral wall extending upwardly from said bottom, and atubular: guide forming an upward continuation of said column and removably arranged upon the same within saidtop portion.

A. A sterilizing tank comprising an upper enlarged portion, alower contracted portion, and a cover consisting of an outer annular portionprovided with means for suspending the articles to be immersed in the liquid, and an inner movable portlon, substantially as set forth, v
